DEVICE FOR REMOVING AXLE-NUTS.

Specification of Letters Patent.

Patented Oct. 3, 1905.

Application filed June 4, 1904- Serial No. 212.589.

T 0 (ZZZ, whom, it 7771(02/ concern:

Be it known that we, JOHN J. MCDONALD and DOUGALD J. MGGILLIVRAY, citizens of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Devices for Removing Axle Nuts; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the ac companying drawings, and to numerals of reference marked thereon, which form a part of this specification.

The objects of this invention are to provide a device which can be used instead of the ordinary wrench for removing the axle-nuts of vehicles-as. for instance, in greasing the axles; to provide such a device which will clamp the nut to the hub, and thus enable it to be turned upon the axle by turning the wheel; to thus enable increased purchase to be brought upon the nut; to obviate separating the nut from the wheel at all, as by an ordinary wrench, and thus to avoid handling a wrench and the nut, dropping the nut, or soiling the hands; to secure such a device which shall be compact and occupy little space when in use upon a wheel and when detached, and to obtain other advantages and results, some of which may be hereinafter referred to in connection with the description of the working parts.

The invention consists in the improved axle-nut wrench and in the arrangements and combinations of parts of the same, all substantially as will be hereinafter set forth and finally embraced in the clauses of the claim.

Referring to the accompanying drawings,

in which like numerals of reference indicate corresponding parts in each of the several figures, Figure 1 is a side elevation of a hub to which our device is applied, a portion of said hub and also the device bein in central section to disclose the position 0 the axlenut more clearly. Fig. 2 is a cross-section taken upon line cc, Fig. 1. Fig. 3 is an edge view of our improved device, partly in section, to illustrate the means for temporarily clamping to a hub; and Fig. 4 is a detail section upon line y, Fig. 3.

In said drawings, 2 indicates any ordinary vehicle-hub providing a box or bearing 3 for the axle 4 and having at its outer end a pcripheral flange 5, the end of the axle being adapted to receive a nut 6, all as is common in the art.

Our improved device comprises a cylindrical body portion 7, adapted to fit easily within the flange 5 of the hub and having at its edge a rim 8 to engage the said flange 5 and serve as a stop. The said cylindrical body portion is centrally recessed at its inner end, or end away from the said rim 8, to receive the axle-nut 6, and two of the opposite side walls of the said recess 9 are perforated, as at 10, to receive clamping-shoes 11, which slide in the perforations. The outer ends of said shoes 11 are rounded on the curve of the hub and serrated, as at 12, to engage the flange 5, while their inner ends normally project a little into the recess 9, so as to be engaged by the corners of the nut as the same starts to turn in said recess. Preferably the said shoes 1 1 are held normally inward by means of leaf springs 13 projecting from the body portion 7 of the device into recesses 14 of the shoes 11. Furthermore, the side walls of the central recess 9 of the body portion 7 are convex in wardly to facilitate the operation of our improved device, as next described.

In use the device is applied to a hub and then the wheel turned, the first part of which turning causes the ends of the shoes 11 to ride along the sides of the nut toward its corners, thus forcing the said shoes radially outward into biting engagement with the hub. Said hub thus limits movement of the shoes, and they then force the nut to turn with the wheel, as will be understood. The wheel is removed from the axle either entirely or partially, with the nut firmly connected thereto by our device, and when again returned to its place it is necessary only to turn the wheel in the opposite direction to screw the nut again upon the axle. The nut therefore does not have to be handled at all and is always in position or centered with respect to the axle.

To avoid any possibility of the device falling out of the hub before it roperly engages the same, as in case it shou d fit loosely, we may sometimes provide means for temporarily securing it to the hub. In the drawings we have illustrated a construction for this purpose consisting of an eccentric 15,

mounted upon the shaft 16, journalcd near one edge of the body portion 7, which body portion is slotted, as at 17, to accommodate the eccentric. The eccentric is fast upon the shaft 16, and said shaft is provided at its outer end with a finger-piece 1.8, by means of which it can be turned to engage the eccentric with the hub-flange Obviously by the use of our invention great convenience and cleanliness are secured in the operation of greasing or oiling a vehicle, and at the same time the work is greatly expedited. There are no essential parts of our device which project outward from the end of the hub, and therefore the operator may stand close to the wheel. Moreover, all the operating parts of the device are covered and inclosed, so that they cannot be injured in any way nor get against the users clothes to injure the same.

Having thus described the inventionm'hat we claim as new is 1. An axle-nut wrench having a body portion adapted to enter the end of a hub and being centrally recessed at its end to receive the axle-nut, and shoes projecting radially through the walls of said body portion and being adapted at their inner ends to be engaged by said nut.

2. An axle nut wrench having a cylindrical body portion adapted to enter the end of a hub, said body portion being centrally recessed at its inner end to receive the axlenut and having perforations extending radially through the walls of said recess, and shoes seated in said perforations to slide therein, said shoes being adapted at their inner ends to engage the axle-nut.

3. An axle nut wrench having a body portion adapted to enter the end of a hub and receive at its inner end the axle-nut, said body portion providing radial slideways, and shoes mounted in said. slideways and adapted to engage at their outer ends the hub and at their inner ends the axle-nut, and means for retaining said shoes in their slideways.

4. An axle-nut wrench comprising a body portion adapted to enter the end of the hub and having a recess corresponding to the axle-nut in shape and adapted to loosely receive the same, and shoes adapted to slide in perforations cut through the opposite walls of said recess, said shoes being adapted at their outer ends to engage the hub and at their inner ends to engage the aXlenut.

5. An axle-nut wrench comprising a body portion adapted to enter the end of the hub and having at its inner end a substantially square recess adapted to loosely receive the axle-nut, two of the opposite walls of said recess being perforated, shoes arranged to slide in said perforations and being adapted at their outer ends to engage the hub and at their inner ends to engage the axle-nut, and means for retaining said shoes in their slideways.

6. In an axle-nut wrench, the combination of a circular body portion adapted to fit into the end of the hub and receive the axle-nut, shoes thereon adapted to be slid radially by said. nut into engagement with the hub, and means independent of said shoes for clamping the wrench to a hub.

7. In an axle-nut wrench, the combination with a body portion adapted to enter the end of the hub and recessed to receive the axle-nut, and shoes arranged to slide radially on said body portion and adapted to be engaged at their inner ends by the axle nut and to engage at their outer ends a hub, of independent clamping means adapted to temporarily fasten the wrench to the hub, and a finger-piece for operating said clamping means.

8. An axle-nut wrench having a body portion adapted to enter the end of a hub and being recessed at its inner end and also providing a radial slideway, and a shoe mounted in said slideway and adapted at its outer end. to engage the hub and at its inner end. to pro ject into the said recess.

9. An axle-nut wrench having a body portion adapted to enter the end of a hub and receive at its inner end the axle-nut, said. body portion providing radial slideways, and shoes mounted in said slideways and adapted to engage at their outer ends the hub and at their inner ends the axle-nut.

In testimony that we claim the foregoing we have hereunto set our hands this 4th day of June, 1904.
